B82790S0253N201

Overview

The B82790S0253N201 is a current-compensated ring core double-wound common mode choke manufactured by EPCOS - TDK Electronics. It features a ferrite core and is designed for data line applications. The component has a typical common mode inductance of 25µH at 100kHz, a rated current of 500mA, and a rated voltage of 80V DC or 42V AC. The typical DC resistance is 110mΩ.

Feature Summary

• Current-compensated ring core construction with bifilar winding
• Case material is flame-retardant according to UL 94 V-0 standards
• Suitable for reflow soldering processes

Applications

• Suppression of asymmetrical interference coupled into lines
• Data line filtering for telecommunications equipment
• xDSL signal line protection

Procurement Notes

Verify the specific suffix N201 against the manufacturer's latest datasheet to confirm terminal plating and packaging specifications. Ensure the selected variant meets the required AEC-Q200 qualification if automotive compliance is necessary for the target application environment.

Selection Notes

Select this component when designing circuits requiring suppression of asymmetrical interference on data lines while allowing data signals to pass unaffectedly. Consider the 500mA rated current and 110mΩ DC resistance for power loss calculations in the signal path design.

Part Context

This component belongs to the B82790 series of common mode chokes from EPCOS - TDK Electronics. These devices are engineered for telecommunications and data transmission applications, providing electromagnetic compatibility by filtering out unwanted noise without distorting the intended data signals.

Replacement Considerations

Check for direct substitutes within the B82790 series with different inductance values or current ratings. Verify pinout compatibility and physical dimensions before replacing with components from other manufacturers offering similar ferrite ring core designs.
